The Seven Year Itch (1955) on Netflix

In summertime in Manhattan, the plain and average Richard Sherman (Tom Ewell) sends his wife and son for vacation in the country. Sherman is the key man of a publishing firm, Brady & Company, which publishes cheap pocket books. The faithful Sherman has a routine life with his family and dreams on being successful with women. When a beautiful and sexy blonde lodges the upstairs apartment of his small building, Sherman first opens the front door for her and then he invites her to have a drink with him after the fall of her tomato vase on his chair. Along the days, he spends some time with the girl and feels tempted by her, but later he misses his family and travels to meet them.
